Answer:
-2
Step-by-step explanation:
z - 7 ≥ 0
z ≥ 7
| z - 7 | = z - 7, z ≥ 7
| z - 7 | = -z + 7, z < 7
z - 9 ≥ 0
z ≥ 9
| z - 9 | = z - 9, z ≥ 9
| z - 9 | = -z + 9, z < 9
| z - 7 | = -z + 7
| z - 9 | = -z + 9
|z - 7| - |z - 9|
-z + 7 - (-z + 9)
-z + 7 + z - 9
= -2

When Digitalis knows that it'll sell many of the processors, it's expected to make money since there's a higher probability that it's not defective.
How to illustrate the probability?Since the processor is sold for $3300 and a profit of $429 is made, the selling price will be:
= $3300 - $429
= $2871
In this case, there's a 13% chance that it's defective and 87% that's it's not defective. Therefore, it's expected to make money since there's a higher probability that it's not defective.

Find an equation for this graph.
Two similar spheres have a scale factor of 2:5. What is the ratio of their surface areas?
Answer:
4:25
Step-by-step explanation:
Sphere surface area = 4 pi r^2
now change r to 2.5 r ( to maintain the 2:5 ratio)
area2 = 4 pi (2.5 r)^2 = 6.25 * 4 pi r^2
so ratio of surface areas is 1 : 6.25 = 4:25
If two similar spheres have a scale factor of 2:5. Then the ratio of their surface areas will be 4 / 25.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Two similar spheres have a scale factor of 2:5.
Let the r₁ and r₂ be the radius of the spheres. Then we have
r₁ / r₂ = 2 / 5
Then the surface area of the sphere is given as
Surface area = 4πr²
Then the ratio of their surface areas will be
[tex]\rightarrow \dfrac{4\pi r_1^2 }{4\pi r_2^2} = \left (\dfrac{r_1}{r_2} \right )^2[/tex]
Then we have
→ (2 / 5)²
→ 4 / 25

Find the dependent value
for the graph
y = 12 + 5x
when the independent value is 3.
y = [?]
Answer:
Y = 27
Step-by-step explanation:
In the equation (y = 12 + 5x) the X is the independent value. When you replace this by 3 you will multiply 3*5 which will give you 15 and then you will want to add 12 as that is your y intercept. Giving the value of your Y a 27, or the point would be (3,27)
Find the amount of sheet metal needed to form a conical funnel of base radius 30 cm and vertical height 50 cm, allowing for a 0.5 cm overlap at the join
The amount of sheet metal needed to form the conical funnel is 5525 cm²
How to determine the amount of sheet?The given parameters are:
Radius, r = 30 cmVertical height, h = 50 cmOverlap = 0.5 cmStart by calculating the slant height (l) of the cone using:
l = √(r² + h²)
This gives
l = √(30² + 50²)
Evaluate
l = 58.31
The lateral surface area of the conical funnel including the overlap is then calculated as:
A = πrl + Overlap * l
This gives
A = 3.142 * 30 * 58.31 + 0.5 * 58.31
Evaluate
A = 5525.4556
Approximate
A = 5525
Hence. the amount of sheet metal needed is 5525 cm²

1. Find the least common multiple of x² + x-12 and x² + 2x - 15
Least Common Multiple = (x-3) (x+5) (x+4)
Step-by-step explanation:
First we solve for x² + x-12
Factorise=> x² + 4x - 3x - 12
Taking common=> x ( x+4 ) - 3 (x+4 )
=> (x-3) (x+4)
Now we will solve for x² + 2x - 15
Factorise=> x² + 5x - 3x - 15
Taking common=> (x-3) (x+5)
we see here (x-3) is common in both the equations so We write it only 1 time as we have to find least common multiple .
Ans. Lest common multiples are = (x-3) (x+5) and (x+4)
